Frequently asked questions about C05CA
What does C05CA mean?
Brake Master Cylinder Piston Position Sensor A Circuit Voltage High. The control module detected that the Brake Master Cylinder Piston Position Sensor A voltage stayed above the expected range.
Is C05CA generic or manufacturer-specific?
C05CA is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove C05CA at file level?
Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether C05CA is removable in your case.
